Heat Treatment


Bolt’s Metallizing, CWST offer heat treating services to fit your needs like Precipitation Hardening, Tempering, Stress Relieving, Solution Annealing, Aging and Fusing processes. Bolt’s uses a wide variety of heat treatment techniques designed to increase the hardness, strength, and fatigue life of metal parts and components. We specialize in providing a range of top- grade heat-treating services for customers with aluminum, steel, specialty and tool steel alloys, or super alloys up to 2400F with inert gas quenching if required. No matter what processes your components need to go through to obtain the durability and corrosion resistance you need, we can get the job done. From our years in the business, we understand that many of our customers are working to meet tight deadlines or have a very precise production schedule that they need to adhere to in order to meet their objectives. We can work flexibly and have the capacity to meet short turnaround times. Our facility is NADCAP certified and calibrated to the stringent requirements of AMS 2750.

Bending, welding, grinding, rolling, cold working, stamping, and other operations, can introduce new stresses into the structure of a metal part. Stress relieving is a heat treatment process designed to relieve residual stresses caused by different types of manufacturing process. This process must be controlled based on the metal or alloy to determine the temperature reached and duration of the heating and the cooling process. Our experience and state-of-the-art facilities allow for precise, controlled heat treatment for stress relieving a wide variety of alloys. We also ensure all our processes, including stress relieving steel, is constantly monitored and tracked for quality control throughout the process and our furnaces are all calibrated to AMS 2750, the most stringent Aerospace standard.
